To all whom, it may concern:

Be it known that I, GUSTAVOS HEIDEL, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented certain new and useful Improvements in Batteries, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention relates to an improvement in batteries; and, brieflystated, it consists in a construction wherein one element of the batteryis formed by the cell thereof and the other element is formed by anelectrode of suitable construction located in the cell with the chemicalsolution, which acts upon the materials of the cell and electrode in thesame manner as such chemicals act upon two electrodes where,

as is'commonly the case, the cell is of non-ac tive material.

The objects of my invention are manifold and comprise reduction in thesize of batteries, reduction in weight, decrease in number of parts, andconsequent reduction in cost of manufacture and decrease in number ofparts necessary to be handled in manipulating the battery. Thesefeatures are of essentialimportance, more particularly in storagebatteries, especially those used upon motor-vehicles, where economy inspace and weight of batteries is material.

My invention consists in features of nov-1 elty hereinafter fullydescribed, and pointed made of.

out in the claims.

Figure I is a perspective view illustrating my improved battery. Fig. IIis a vertical sectional view of the battery-cell. Fig. III is anenlarged detail view, partly in section, of a fragment of the cell. Fig.IV is'a view, partly in cross-section, of a fragment of the cell,showing a modification.

The cell of the battery is composed of electro-active material of. anysuitable description, such as zinc, lead, and carbon or others that theelectrodes" of batteries are usually The cell is provided with abinding-post connection 2, adapted to receive one of the terminal wires.For the purpose of insulating the cell at its exterior from surroundingobjects into which the electric current may be discharged I provide ribs3, lo-

cated at intervals aboutthe-exterior of the cell at sides and bottom,and form recessed bosses 4 upon these ribs, into which are insertedinsulator-plugs 5. 'The plugs 5 may be of rubber, wood, cork, or anyother suitable non-conductor of electricity.

6 designates an electrode of suitable construction and design arrangedWithin the cell 1. I have shown but one electrode; but it is obviousthat any greater number may be employed in the same cell, and in'practice a greater number would usually be employed.

It is obvious that for the practical operation of the battery it isnecessary that the electrodes contained in the cell must be insulatedfrom such cell. To provide for such insulation, I place insulator-strips7 within the cell, suitably maintained in the Wall thereof. These stripsmay be of anysuitable material such as rubber, wood, or cork-and theyare preferably provided with grooves 7 into which the electrodes 6 areinserted to maintain them in upright position and prevent them fromfalling into contact with each other.

In some instances I may utilize insulatorplugs 8 on the interior of thecell 1 in addition to the strips 7, as seen in Fig. II, and in. someinstances the strips 7 may be dispensed with and the plugs .8 be usedentirely in lieu thereof, .as illustrated in the modification shown inFig." IV. The interior of the cell-walls is preferably of cellularformation, as shown, in order to expose a" maximum of surface for theaction of the chemicals upon the electroactive material of the cell.

I claim as my invention- 1, As a new article of manufacture abattery-cell of conductive material provided with insulators projectingat intervals from the exterior of the cell, substantiallyas and for thepurpose stated.

2. A battery comprising a cell of electroactive material forming oneactive element thereof, an electrode located in said cell and formingthe other active element, and insulators arranged upon the exterior ofsaid cell,

ranged in said cell, means for insulating said lating said electrodefrom said cell, ribs ar electrode from said cell, and insulators 10-ranged 0n the exterior of said cell, recessed lo cated upon the exteriorof said cell and probosses on said ribs, and insulator-plugs in jectingat intervals therefrom, substantially said bosses, substantially asdescribed.
